PS Technology, a wholly owned subsidiary of Union Pacific, has acquired the Yard Control Systems division of Ansaldo STS USA, which is based in Norristown, Pa. The acquisition boosts PST's capabilities by adding rail yard process control and automation solutions.

"Rail yard optimization is important for railroads to increase efficiency, create faster delivery times and help customers compete in a global economy," said Ashok Fichadia, PST CEO. "Efficient yards are critical for managing the forecasted freight rail traffic growth in coming years."

"This acquisition will allow us to continue to expand our business of providing railroad industry technology solutions that drive safety, service and efficiency, ultimately bringing greater value to customers," said Ed Williams, PST president. "We are fortunate to retain the entire Yard Control Systems staff to maintain continuity for existing customers and build a strong foundation for future growth."
